SPECIFICATION forming part; of Letters Patent No. 375,719, datedDecember 27, 1887.

Application tiled October 14, 1887. Serial No. 252,316. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. VVYATT, a citizen of the United StatesofAmerica, residing at Princeton, in the county of Caldwell and State ofKentucky, have invented certain new and useful Improvements inCultivators; and I do hereby declare the following to beafull, clear,and exact description of the invention, such aswillenable othersskilledin the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to letters orfigures of reference marked thereon, which form a part ofthisspecification.

My invent-ion relates to an improvement in cultivators; and it consistsin the novel con struction and arrangement of the parts thereof, whichwill be more fully hereinafter described, and pointed out in the claims.

The object of my invention is to provide a cultivator for use in theformation of hills for planting tobacco and other products requiringhills, the construction and operation thereof being simple andettectivastrong and durable, easily handled, and readily understood.Iattain this object by the construction illustrated in the accompanyingdrawings, wherein like letters of reference indicate similar parts inthe several views, and in which- Figure 1 is a perspective view of myimprovement. Fig. 2 is a longitudinal vertical section thereof.

B indicates the main beams, which diverge from their front meetingpointtoward the rear thereof, and have curved plows E secured thereto,which are mounted atan angle and inwardly toward each other. These plowsare formed of such curvature that the soil will be thrown inward therebyand form a central ridge.

Supplemental beams C are secured to the beams .B and extend to the rearofthe saidlatter beams and are provided with a series of apertures, c,at their rear portion. These beams() are constructed in the form asshown, converging at their front and rear portions and distended attheir central portion. A pivot-rod, passes through the forward endsthereof and through the beams B and lower ends of the handles A. Therear portions of the said beams O are curved downwardly, and

at the upper beginning of said curve they are supported on a tie-rod, B,uniting the beams B at this point. The rear lower ends of the beams Gare secured to the outside surface of two former plates or followers,FF,which have angle-plates fsecured thereto and projecting upwardtherefrom and form bearings for the shaft ofa roller, F, which ismounted between said plates F. These plates F are inclined outwardly,the space between the same being wider at their bottom than at their topportions. On the said beams 0 above the plates F a tie-brace, O, ismounted, which prevents the plates F from separating by strain broughtto bear thereupon.

Secured to the rear sides of the plows E are irregular angular metallicstrips D D, which extend inward and are secured to one set of the holes0 of the beams C,and then extend upward and are secured to the handlesA. The upper ends of the strips D are formed with a series of apertures,07, so as to permit of a ver tical adjustment with the plow-handles,said strips being also adjustable with relation to the holes 0 in thebeams C. By this means both a vertical and lateral adjustment of theparts as thus connected is readily obtainable, which would narrow thehillformed and to some eX- tent decrease the depth of cut of the plowsE.

Between the front converging ends of the beams B a draft iron or link,G, is pivotally mounted, but clamped stationarily when the beams arejoined, as hereinbefore described. The said link G is formed with aseries of forward apertures, g, at dilierent elevations and is adaptedto rest on a cross-pin, g,which holds and bracesit at an inclination.The rear of said link is also provided with an aperture, 9 which permitsof a variation in its longitudinal adjustment. By attaching the link ofthe whiffletree in the lowermost aperture 9 the tendency will be to drawthe plows deeper into the ground, and an upper adjustment of thewhiiiletree-link will lessen this tendency.

In the use of my improvement the plows E turn the soil inward toward thecenter and the plates F press the sides of the ridge thus formed andslightly compact the same, and the top roller, F, rides over the top ofthe ridge and presses the same downward at the same time that the platesF press it upward.

The width between the plates F and the rear of the plates E is equal,and the width of the cutis uniform with the ridge formed. The advantagesof my improvement consist in the simplicity of operation and positive result, the draft necessary being but the power ofa single animal. Thecultivator can be used to advantage on hillsides and on irregularsurfaces.

The simple construction of my improvement and its general utility beingobviously apparent,it is unnecessary to further enlarge upon the sameherein.

Having thus described my invention, what I claim as new is- 1. Thecombination of the plowbeams B, the curved plows E,secured thereto andset at inwardly-opposing angles, the supplemental beams G, pivoted tothe beams B and having the rear tie-brace, O, the tie-rod B, the inclined plates F, having angular platesf, and the roller F between saidplates and the strips D, said beams O and strips D being adjustable, asset forth, with the parts to which they are connected, substantially asdescribed.

2. In a cultivator, the combination of the diverging plow-beams, thecurved angularlyset plows, the supplemental adj ustable beams pivoted tothe main diverging beams, the in- JOHN R. XVYATT.
